Darren Bannister, 45, from Sleaford had his hair shaved off on August 30, along with his brother Jason, 43, who now lives in Derby.
Macmillan has been helping their younger brother Mark, 38, with his fight against cancer, diagnosed earlier this year.
Darren said: “He is undergoing treatment at Nottingham and is looking much better.
“I want to do my litle bit to help those other families affected.”
Mark was invited to do the honours and shave off his brothers’ hair. Darren, left, who works for Jobcentre Plus, is pictured with Mark (centre) and Jason (right) after the shave. He said: “I want to do my little bit that will be a huge help to all those other families affected. You never know what life is going to throw at you.”
